BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a computer program product, system, and method for controlling moveable robot blocks to dynamically form a barrier.

2. Description of the Related Art

Floods in the United States cause billions of dollars in property damage and loss of life. The most common form of flood control involves building barriers using sandbags, which are cheap and usually effective. Constructing flood barriers from sandbags is very labor intensive and when they fail to control the water flow due to a storm, they fail catastrophically. If the flood severity is higher than expected, the sandbag barriers are not flexible enough to adjust to meet the actual needs of flood conditions. It takes long time and significant effort to build effective sandbag barriers and to remove the sandbag barriers when the danger has subsided.

There is a need in the art for improved techniques for constructing barriers to prevent flood damage.

DETAILED DESCRIPTION

As weather conditions rapidly change at different areas where barriers are constructed, there may be a need to move barriers formed at one location to another. However, this dynamic adjustment to increase or decrease a barrier size is impractical when the barrier is formed of sandbags.

Described embodiments provide improved computer technology to create a barrier and dynamically adjust a size of a barrier based on estimated weather conditions and environmental conditions detected by moveable robot blocks, such as self-assembling robots that independently move to construct the barrier, such as a flood barrier, at geographical locations where flood barriers are needed to protect property and lives.

Described embodiments provide improved technology for constructing barriers by providing an assembly management system that generates a barrier plan indicating a placement of moveable robot blocks at locations in a coordinate system to form a barrier in a geographical area. The coordinates system indicates locations for the moveable robot blocks to form the barrier. The size of the barrier may be determined by weather reports from a weather service that are used to determine a water flow at geographical locations. After generating the barrier plan, commands are transmitted to the moveable robot blocks deployed in the geographical area where the barrier is to be formed to cause the moveable robot blocks to move to the locations in the coordinate system in the barrier plan to form the barrier.

Further, with described embodiments, the moveable robot blocks may transmit environmental parameters sensed by sensors in the moveable robot blocks, such as water pressure, sensed water, etc., to the assembly management system. The assembly management system may determine whether the environmental parameters satisfy an environmental condition, such as water level to high or low, water pressure to high or low, water detected in the interior of the barrier, etc. Upon the environmental condition being satisfied, a revised barrier plan is dynamically generated to increase or decrease a size of the barrier to adjust to the environmental conditions and commands are sent to the moveable robot blocks to implement the revised barrier plan.

Embodiments of the present invention arise at least partly from a recognition that dynamically constructing or adjusting barriers responsive to predictions or conditions, including weather conditions, for example, may prevent or mitigate flood damage.

Described embodiments further provide operations for a moveable robot block, such as a self-assembling robot, to perform to couple to a barrier to from the barrier and to process environmental conditions with an environmental sensor, such as a water pressure sensor included in the moveable robot block. The moveable robot block processes a sensed environmental parameter, such as a water pressure, presence of water, etc., to determine a satisfied environmental condition to then transmit to the assembly management system to determine whether a revised barrier plan needs to be generated based on environmental conditions detected by the moveable robot block. This provides improved robot and computer technology for moveable robot blocks to form a barrier and to report on detected environmental conditions to the assembly management system managing the formation of the barrier to dynamically determine in real time whether adjustments need to be made to a size of the barrier to respond to detected environmental conditions requiring that the barrier be expanded to address additional environmental stress, i.e., increased flood waters, or reduce a size of the barrier due to an abatement in environmental conditions, flood waters receding.

FIG. 1 illustrates an embodiment of a barrier assembly environment having an assembly management system 100 that communicates with numerous moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) over a network 104, such as self-assembling robots capable of moving to couple with each other to form a predefined structure. The assembly management system 100 includes a processor 106 and a memory 108. The processor 106 may comprise one or more central processing units (CPUs) or a group of multiple cores on a single CPU.

The memory 108 further includes a water flow modeler 110 that receives information on predicted storms and water downfall for a geographical area from an online weather service 112 over the network 104 and estimates water flow and flood risks in the geographical area. The water flow modeler 110 provides estimates of flooding at different geographical locations, including water flow, height, etc., to a barrier plan generator 114. The barrier plan generator 114 estimates barriers that should be deployed in the geographical area of the flood to act as a flood barrier to deploy along a waterway, coastal areas, or any other area where there is a flood risk. The barrier plan generator 114 generates a barrier plan 200 for each barrier to build in the geographical area for flood prevention. The barrier plan 200 specifies a coordinate system for the barrier of locations for the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) identified in a robot database 300 to cause the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) to move to the coordinates for the barrier specified in the barrier plan 200.

The memory 108 further includes a barrier assembly manager 116 to send commands to the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n). In one embodiment, the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) may comprise self-assembling robots. In such a self-assembling robot embodiment, the barrier assembly manager 116 may send to each of the self-assembling robots 500 ₁ the barrier plan 200 having the coordinates of the barrier and the self-assembling robots may use an assembly algorithm to swarm to the coordinates in the barrier plan 200 and couple together to form the barrier. Certain of the self-assembling robots may be positioned as seed robots to define an origin of the coordinate system defined in the barrier plan 200 and the other robots may then use a swarming or fixed self-assembly algorithm to move to coordinate positions of the barrier.

In an alternative embodiment, the barrier assembly manager 116 may send commands to control the movement of the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) to locations in the coordinates of the barrier plan 200 to form the barrier.

The moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) may be of a size suitable for forming blocks in the wall and capable of movement, such as be up to several inches on each side, or larger.

The barrier assembly manager 116 maintains barrier thresholds 400 for environmental conditions to apply to the environmental parameters sensed by the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) that have coupled together to form the barrier. Upon thresholds being satisfied by the measured environmental parameters, the barrier assembly manager 116 may request the barrier plan generator 114 to generate a revised barrier plan 200 _(R) that increases or decreases the size of the barrier depending on the detected environmental conditions.

The program components 110, 114, and 116 are shown in FIG. 1 as program code loaded into the memory 108 and executed by the processor 106. Alternatively, some or all of the functions may be implemented in hardware devices in the system 100, such as in Application Specific Integrated Circuits (ASICs) or executed by separate dedicated processors.

The arrows shown in FIG. 1 show a data flow between the components 110, 114, 200 in the memory 108.

The memory 108 may comprise a suitable volatile or non-volatile memory devices, including those described above.

FIG. 2 illustrates an embodiment of a barrier plan 200 generated by the barrier plan generator 114 to construct a barrier and includes: a barrier plan identifier (ID) 202; a barrier location 204 indicating a geographical location of the barrier, such as Geographical Positioning Signals (GPS); barrier dimensions 206; and barrier coordinates with respect to an origin point that comprise the barrier, such as x, y, z coordinates in three-dimensional space.

FIG. 3 illustrates an embodiment of a robot record 300 _(i) in the robot database 300 having information on robots deployed at barriers, including a robot ID 302; a robot network address 304 to which commands can be transmitted; a GPS location 306 of the robot; a barrier plan ID 308 of the barrier to which the robot is deployed. The barrier assembly manager 116 may use the robot records 300 _(i) to determine robots 500 _(i) deployed for a barrier identified by a barrier plan 308 and communicate commands and the barrier plan 200 to the robots defined by the robot records 300 _(i).

FIG. 4 illustrates an instance of a threshold 400 _(i) that the barrier assembly manager 116 may use to determine whether environmental parameters sensed by the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) satisfy a threshold type 402, such as a water height level, water pressure threshold, presence of water, etc., and a low mark 404 (such as a low water pressure threshold or low water height) used to determine whether the barrier should be reduced in size and a high mark 406 (such as a high water pressure threshold or high water height) used to determine whether the barrier should be increased in size to address a high level of water pressure or water height. Alternatively, there may be just one threshold for a threshold type 402.

FIG. 5 illustrates an embodiment of a moveable robot block 500 _(i) that includes a moveable robot block housing 502 surrounded by a waterproof casing 504. The housing 502 includes a processing unit 506 coupled over a bus interface 508 to a battery 510 supplying power, movement motors 512 that allow the robot block to pivot along multiple degrees of freedom; and coupling mechanisms 514 to allow the robot block 500 _(i) to couple with other robot blocks, such as retractable claws used to attached to other blocks and magnets, that when activated can be drawn to other blocks; and environmental sensors 516, such as a water sensor, water pressure sensor, etc. to sense an environmental parameter, such as water. The processing unit 506 includes a robot controller 518 to control the movement and coupling and decoupling with other robots 500 _(j). The processing unit 506 stores a barrier plan 200 received from the assembly management system 100 that the robot controller 518 uses to cause the movement motors 512 to move the block 500 _(i) to a location in the coordinate system 208 specified in the barrier plan 200.

The moveable robot block 500 _(i) may include a wide area network adaptor 520 to communicate over the network 104 with the assembly management system 100 and other moveable robot blocks 500 _(j) and a local robot network adaptor 522 to communicate with other moveable robot blocks 500 _(j) to form the barrier and within the barrier. The wide area network adaptor 520 may implement WiFi® technology, cellular technology, such as 2G, 3G, 4G, etc. networks, and other wireless communication technologies. The local robot network adaptor 522 may implement a WiFi®, MiFi®, Bluetooth®, tethering, and other wireless communication technologies. (Bluetooth is a registered trademark of Bluetooth Special Interest Group throughout the world Wi-Fi is a registered trademark of the Wi-Fi Alliance; MiFi is a trademark of Novatel Wireless throughout the world.)

The robot block 500 _(i) may comprise various shapes, such as a square, rectangle shape, a polyhedron or other suitable shape to couple to other robot blocks to form a waterproof barrier. Further, the robot blocks 500 _(i) on an outer layer of the barrier may couple to other robot blocks in the outer layer to form a water tight seal between the robot blocks 500 _(i) that is impervious to water. Moveable robot blocks 500 _(i) in the inner layers of the barrier may or may not form tight water impervious couplings.

In certain embodiments, the robot controller 518 may implement a self-assembling robot to be capable of coordinating with other robots to move to a coordinate in the barrier plan 200 using self-assembling and swarming algorithms.

The robot controller 518 in FIG. 5 may comprise program code loaded into a memory of the robot controller 518 and executed by a processor in the robot controller 518. Alternatively, some or all of the functions of the robot controller 518 may be implemented in hardware devices in the system 100, such as in Application Specific Integrated Circuits (ASICs) or executed by separate dedicated processors.

FIG. 6 illustrates an embodiment of operations performed by the water flow modeler 110, barrier plan generator 114, and barrier assembly manager 116 to generate a barrier plan 200 and control the moveable robot blocks 500 i. Upon initiating (at block 600) an operation to generate a barrier plan 200, the assembly management system 100 receives (at block 602) information on a predicted storm, such as information of date, time, and intensity from an online weather service 112 or via user manual entry and invokes (at block 604) the water flow modeler 110 to estimate a level of water flow in a geographical area due to storm predictions. The water flow modeler 110 provides (at block 606) the estimate of water flow to the barrier plan generator 114 to determine dimensions of a barrier to function as a flood barrier in the barrier location 204 for the storm indicating a placement of moveable robot blocks at barrier coordinates 208 to form a barrier in a geographical area or barrier location 204 in a barrier plan 200. The barrier assembly manager 116 processes the barrier plan 200 to transmit (at block 608) commands to the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) deployed at the barrier location 204 to cause the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) to move to the locations comprising the barrier coordinates 208 in the barrier plan 200 to form the barrier.

In embodiments where the robots 500 _(i) comprise self-assembling robots, the commands would include the barrier plan 200, including coordinates 208, to cause the robots to move to the barrier coordinates 208 to form the barrier.

The embodiment of FIG. 6 provides improvements to computer technology for constructing a barrier by generating a barrier plan having barrier coordinates generated based on current weather and water flow conditions to be capable of flood prevention for an upcoming storm. Described embodiments allow dynamic construction of a barrier by deploying robot blocks to the location of the barrier where they may then be controlled to move to coordinates of the barrier to form the barrier needed for flood prevention.

FIG. 7 illustrates an alternative embodiment of operations performed by the barrier assembly manager 116 to directly control the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) to move to barrier coordinates 208. Upon initiating (at block 700) operations to transmit commands to directly control the robot, the barrier assembly manager 116 communicates (at block 702) with a plurality of moveable robot blocks 500 _(i) deployed in the barrier location 204 where the barrier is to be formed to determine geographical locations of the moveable robot blocks 500 _(i). An optimization program generates (at block 704) a swarm plan having an assignment of the moveable robot blocks deployed in the barrier location to the barrier coordinates 208 in the barrier plan 200 to minimize distances the moveable robot blocks 500 _(i) move to reach their assigned barrier coordinates in the barrier. The barrier assembly manager 116 transmits (at block 706) move instructions to the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) deployed in the geographical area to cause the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) to move to their assigned coordinates and couple to other moveable robot blocks to form the barrier.

With the alternative embodiment of FIG. 7, the barrier assembly manager 116 controls the movement of the moveable robot blocks 500 _(i) by directing them to assigned coordinates 208 in the barrier plan 200.

FIG. 8 illustrates an embodiment of operations performed by the barrier assembly manager 116 upon receiving (at block 800) environmental parameters transmitted over the network 104 from sensors 516 from the moveable robot blocks 500 _(i), such as water pressure, water presence, etc. If (at block 802) the received environmental parameters satisfy an environmental condition, such as a low 404 or high 406 mark in a threshold 400 _(i), then the barrier plan generator 114 generates (at block 804) a revised barrier plan 200 _(R) having revised coordinates for moveable robot blocks to form a revised barrier. If (at block 806) the revised barrier is increased in size, then the barrier assembly manager 116 transmits (at block 808) commands to additional moveable robot blocks that are deployed in the geographical area that are not part of the barrier to cause the additional moveable robot blocks to move to coordinates 208 added in the revised barrier plan 200 _(R) not currently occupied by a moveable robot block 500 _(i) to form the revised barrier. If (at block 806) the barrier is decreased by the revised barrier plan 200 _(R), then the barrier assembly manager 116 transmits (at block 810) commands to the moveable robot blocks forming the barrier according to the previous barrier plan 200 to cause moveable robot blocks at coordinates in the barrier plan that do not comprise revised coordinates 208 in the revised barrier plan 200 _(R) to decouple from the barrier to form the smaller revised barrier.

With the embodiment of FIG. 8, the barrier assembly manager 116 is capable of responding to changes in sensed environmental parameters at the moveable robot blocks 500 ₁, 500 ₂ . . . 500 _(n) forming the barrier and optimize the barrier by either adding layers of coordinates for additional moveable robot blocks to couple to the barrier to be able to withstand detected harsher environmental conditions and remove layers of coordinates to cause moveable robot blocks to decouple from the barrier if environmental conditions subside. This allows for dynamic adjustment to the barrier as needed, and moveable robot blocks 500 _(i) decoupled from the barrier may then be deployed to other barriers at other geographical locations where they are needed.

FIGS. 9, 10, and 11 provide further embodiments to adjust the size of the barrier for specific environmental conditions for a barrier deployed for flood prevention.

FIG. 9 illustrates an embodiment of operations performed by the barrier assembly manager 116 to determine whether to adjust the height of the barrier based on water pressure sensors 516 detecting a height of the water level. Upon receiving (at block 900) water pressure measurements from water pressure sensors 516 in the moveable robot blocks 500 _(i) arranged in stacked rows to form the barrier, the barrier assembly manager 116 determines (at block 902) a first non-submerged row of the moveable robot blocks comprising a first row of moveable robot blocks from a bottom of the barrier at which the water pressure sensed indicates the first row of the moveable robot blocks is not submerged in water. A height of the water level is determined (at block 904) based on a height of the first non-submerged row of moveable robot blocks 500 _(i), where the height would be the height of the row of moveable robot blocks immediately below the first non-submerged row from the base of the barrier. If (at block 906) the height of the water level is less than a low water mark 404, then the water level has subsided and the barrier plan generator 114 is invoked (at block 908) to generate a revised barrier plan 200 _(R) to decrease a height of the barrier by removing one or more rows of coordinates from the top of the barrier. Commands are sent (at block 910) to the moveable robot blocks in the barrier to cause at least one row of moveable robot blocks above the low water mark to decouple from the barrier.

If (at block 906) the height of the water is not less than the low level mark 404, but is higher (at block 912) than a high water mark 406, then the barrier assembly manager 116 generates (at block 914) a revised barrier plan 200 _(R) to increase a height of the barrier by adding one or more rows of coordinates to the top of the barrier. Commands are sent (at block 916) to additional robot blocks 500 _(j) not currently coupled to the barrier to move to the barrier to couple to the barrier to increase the height by adding the rows of coordinates according to the revised barrier plan 200 _(R). If (at block 912) the high water mark 406 is not exceed then control ends without adjusting the barrier.

With the embodiment of FIG. 9, the height of the barrier may be adjusted based on a water level detected by the moveable robot blocks 500 _(i) on an outer surface of the barrier adjacent to the flow of water. This allows dynamic adjustment to increase the height if the water level has increased during the storm and threatens to overflow the barrier or to decrease the height if the storm subsides. Decreasing the height by decoupling moveable robot blocks 500 _(i) allows deployment of the blocks at locations where they are more urgently needed.

FIG. 10 illustrates an embodiment of operations performed by the barrier assembly manager 116 to determine whether to adjust a width of the barrier based on water pressure sensors 516 detecting water pressure on the barrier. Upon receiving (at block 1000) water pressure measurements from water pressure sensors 516 in the moveable robot blocks 500 _(i) arranged in stacked rows to form the barrier, the barrier assembly manager 116 determines (at block 1002) whether a water pressure at the barrier, such as an average of water pressure measurements from moveable robot blocks on a surface of the barrier, is less than a low pressure mark 404. If so, the barrier assembly manager 116 invokes (at block 1004) the barrier plan generator 114 to generate a revised barrier plan 200 _(R) to decrease a width of the barrier by removing one or more layers of coordinates from a side of the barrier. Commands are sent (at block 1006) to cause at least one layer of moveable robot blocks 500 _(i) not at coordinates in the revised barrier plan 200 _(R), i.e., at the removed layers of coordinates, forming one side of the barrier to decouple from the barrier.

If (at block 1002) the water pressure is not less than the low pressure mark 404 but greater (at block 1008) than the high pressure mark 406, then the barrier assembly manager 116 generates (at block 1010) a revised barrier plan 200 _(R) to increase a width of the barrier by adding one or more layers of coordinates to a side of the barrier. Commands are sent (at block 1012) to additional robot blocks 500 _(j) not currently coupled to the barrier to move to the barrier to couple to a side of the barrier at the added layer of coordinates to increase the width according to the revised barrier plan 200 _(R). If (at block 1008) the high pressure mark 406 is not exceeded, then control ends without adjusting the barrier.

With the embodiment of FIG. 10, the width of the barrier may be adjusted based on a water pressure detected by the moveable robot blocks 500 _(i) on an outer surface of the barrier adjacent to the flow of water. This allows dynamic adjustment to increase the width if the water level has increased during the storm and threatens to rupture the barrier and to decrease the width if the storm and water flow pressure subsides. Decreasing the width by decoupling moveable robot blocks 500 _(i) allows deployment of the moveable robot blocks at locations where they are needed.

FIG. 11 illustrates an embodiment of operations performed by the barrier assembly manager 116 upon receiving information from water sensors 516 in moveable robot blocks 500 _(i) in an interior of the barrier that water was sensed, which may indicate a breach in the barrier. Upon receiving (at block 1100) water sensed information from moveable robot blocks 500 _(i) in the interior of the barrier, the barrier assembly manager 116 generates (at block 1102) a revised barrier plan 200 _(R) to add layers of coordinates to the barrier to increase dimensions of the barrier to withstand possible leaks indicated by the water sensed in the interior. Commands are sent (at block 1104) to additional moveable robot blocks 500 _(j) not currently coupled to the barrier to move to the added layer of coordinates to couple to the barrier to increase a size of the barrier to implement the revised barrier plan 200 _(R) to increase dimensions of the barrier and its ability to withstand greater water flow or breaches in the barrier.

In the embodiments of FIGS. 9, 10, and 11 using self-assembling robots, the barrier assembly manager 116 may send the revised barrier plan 200 _(R) to the self-assembling robots 500 _(i) to cause them to determine whether to decouple or couple based on the revised plan. In an alternative embodiment, such as shown in FIG. 7, the barrier assembly manager 116 may send commands to direct moveable robot blocks to couple or decouple to the barrier to implement the revised barrier plan 200 _(R).

With the embodiments of FIGS. 9, 10, and 11, the layers of coordinates for moveable robot blocks may be added or removed based on sensed environmental conditions such as water level height, water pressure in the water flow adjacent to the barrier, or water detected internal to the barrier.

FIG. 12 illustrates an illustration of the barrier 1200 formed of moveable robot blocks, such as 1202 to form a barrier to a body of water 1204, such as a flood. An initial barrier 1206 is first formed, and then, after the water 1204 rises, a revised barrier 1208 is formed that is both higher and of greater width. Moveable robot blocks 1210 are positioned near the barrier to move to the barrier 1200 to couple to the barrier 1200.

FIG. 13 illustrates an embodiment of operations performed by the moveable robot block 500 _(i) when receiving a movement command from the assembly management system 100, such as in FIG. 7. Upon the moveable robot block receiving (at block 1300) a command to couple to the barrier, which may comprise the move instructions sent at block 706 in FIG. 7 to move to a location of assigned coordinates in the coordinate system 208, the robot controller 518 controls (at block 1302) movement motors 512 to cause the moveable robot block 500 _(i) to move to the location in the coordinate system to couple to the barrier according to the received command at the indicted coordinates/location.

FIG. 14 illustrates an alternative embodiment of operations performed by the moveable robot block 500 _(i) comprising a self-assembling robot when receiving a barrier plan 200 from the assembly management system 100. The barrier plan 200 indicates a placement of moveable robot blocks at locations in a coordinate system 208 to form a barrier in a geographical area 204. The coordinate system 208 indicates locations for the moveable robot blocks to form the barrier. Upon receiving (at block 1400) the barrier plan with a command to couple to the barrier, via the wide area network adaptor 520 from the assembly management system 100 over the network 104, the robot controller 518 communicates (at block 1402) with external self-assembling robots 500 _(j), over the local robot network adaptor 522, to coordinate movement to a selected location of the locations in the coordinate system 208. The robot controller 518 controls (at block 1404) the movement motors 512 to move to the selected location to couple to the barrier 1200, adjusting the selected location depending on actions by other self-assembling robots 500 _(j) swarming according to an assembly and swarming algorithms to form the barrier according to the barrier plan 200.

FIG. 15 illustrates an alternative embodiment of operations performed by the moveable robot block 500 _(i) to process a revised barrier plan 200 _(R) which specifies a barrier larger or smaller than a previous barrier 200 to which the moveable robot block 500 _(i) is coupled. Upon receiving (at block 1500) a revised barrier plan 200 _(R) to form a revised barrier 1206 occupying a smaller space than the current barrier 1208 to reduce a size of the current barrier 1208, wherein the revised barrier plan 200 _(R) indicates a revised coordinate system 208 for moveable robot blocks to form the revised barrier, the robot controller 518 determines (at block 1502) whether the moveable robot block 500 _(i) is located, while coupled to the barrier, within the revised coordinate system 208 of the revised barrier plan 200 _(R). If so, control ends because the moveable robot block 500 _(i) is part of the revised barrier. If (at block 1502) the moveable robot block is no longer in the coordinate system 208, then the moveable robot block 500 _(i) decouples (at block 1504) from adjacent self-assembling robots to separate from the barrier to form the revised barrier. The robot controller 518 may control the coupling mechanism 514 to decouple from attached adjacent self-assembling robots 500 _(j), such as causing a latch or magnet to disengage from attached self-assembling robots 500 _(j).

FIG. 16 illustrates an embodiment of operations performed by the moveable robot block 500 _(i) to process a water pressure sensed by a water pressure sensor 516. Upon sensing (at block 1600) a water pressure from the sensor 516, the robot controller 518 determines (at block 1602) whether the sensed water pressure indicates the movable robot block 500 _(i) is submerged in water. If so, then the robot controller 518 transmits (at block 1604 to the assembly management system 100 indication that the movable robot block is submerged. If (at block 1602) the sensed water pressure does not indicate submersion, then control ends.

In embodiments where the moveable robot block 500 _(i) communicates with the assembly management system 100, if the movable robot block 500 _(i) is submerged, then it communicate with the assembly management system 100 over the wide area network adaptor 520 if the wide area network adaptor 520 is capable of transmitting through water to space above the water. Alternatively, if submerged, the movable robot block 500 _(i) may communicate via the local robot network adaptor 522 to another movable robot block 500 _(j) that is not submerged or closest to the water line, and the receiving robot block 500 _(j) may forward the transmission to another movable robot block or to the network 104 via the wide area network adaptor 520. In this way, submerged robot blocks may communicate to the assembly management system 100 directly over the wide area network adaptor 520 and network 104 if communication through water is feasible or indirectly by transmitting to adjacent moveable robot blocks through the local robot network adaptor 522.

FIG. 17 illustrates an embodiment of a communication or transmitted environmental condition 1700 sent from the moveable robot block 500 _(i) to the assembly management system 100, and includes a robot identifier 1702 of the transmitting moveable robot block; a barrier identifier 1704 identifying the barrier or barrier plan 200, in which the movable robot block 1702 is deployed; a location in the barrier 1706, such as a coordinate in the barrier coordinate system 208 of the barrier 1702; and an environmental condition 1708 detected at the moveable robot block 200 _(i), such as a water pressure, indication of presence of water or some result of comparing sensed values. The transmitted environmental condition 1700 may be received for processing by the assembly management system 100 according to FIGS. 8, 9, 10, and 11.

FIG. 18 illustrates an embodiment of operations performed by the moveable robot block 500 _(i) to process a water presence detected by a water detection sensor 516. Upon sensing (at block 1800) with water sensor 516 a water presence external to the movable robot block 500 _(i), the presence may be determined for a threshold amount of water, but not necessarily requiring the robot block 500 _(i) is submerged, if (at block 1802) the moveable robot block 500 _(i) is at a location in the coordinate system 208 in an interior of the barrier, i.e., surrounded on all sides by other moveable robot blocks 500 _(j), then the robot controller 518 transmits (at block 1804) to the assembly management system 100 indication that water is detected as an environmental condition 1708 in the transmitted environmental condition 1700. If (at block 1802) the moveable robot block is not in the interior of the barrier, such as on an exterior of the barrier, then control ends.

The transmitted environmental condition 1700 in FIG. 18 may be processed by the assembly management system 100 according to the operations in FIG. 11 to increase the size of the barrier if water is detected in the interior according to FIG. 17, indicating that the barrier is not sufficient to handle the stress of the water flow 1204, resulting in water detected in the interior of the barrier 1206.

FIG. 19 illustrates an embodiment of operations performed by the moveable robot block 500 _(i) to process a water pressure bearing on the exterior of the moveable robot block 500 _(i) sensed by a water pressure sensor 516. Upon detecting (at block 1900) water pressure, if (at block 1902) the sensed water pressure is higher than a high pressure mark, then the robot controller 518 transmits (at block 1904) to the assembly management system 100 indication the water pressure exceeds the high pressure mark as an environmental condition 1708 in the transmitted environmental condition 1700. If (at block 1902) the high pressure mark is not exceeded and if (at block 1906) the sensed water pressure is lower than a lower pressure mark, then the robot controller 518 transmits (at block 1908) to the assembly management system 100 indication the water pressure is lower than the low pressure mark as an environmental condition 1708 in the transmitted environmental condition 1700.

The transmitted environmental condition 1700 in FIG. 19 may be processed by the assembly management system 100 according to the operations of FIG. 10 to generate a revised barrier 200 _(R) to increase the size 1206 of the barrier to a larger barrier 1208 if the water pressure exceeds the high pressure mark or decrease the size of the barrier 1208 to a smaller barrier 1206 if the water pressure is lower than the low pressure mark. Detecting too high of pressure indicates that the barrier needs to be increased due to a risk it will be overwhelmed by the water flow 1204.

FIG. 20 illustrates an embodiment of operations performed by the moveable robot block 500 _(i) to process a water pressure bearing on the exterior of the moveable robot block 500 _(i) sensed by a water pressure sensor 516 to determine if the wall is too low or too high given the water 1204 level. Upon detecting (at block 2000) water pressure, if (at block 2002) the sensed water pressure indicates the moveable robot block 500 _(i) is submerged in water, then a height of the moveable robot block 500 _(i) is determined (at block 2004) based on its location in the coordinate system 208 of the barrier. If (at block 2006) the height is higher than a high water mark, then the robot controller 518 transmits (at block 2008) to the assembly management system 100 the transmission 1700 with indication of robot ID 1702, barrier ID 1704, location in the barrier 1706 and environmental conditions 1708 of a height in the barrier and indication the robot is submerged in water and above the high water mark If (at block 2002) the water pressure sensor 416 indicates the moveable robot block 500 _(i) is not submerged and if (at block 2012) the height is lower than a low water mark, then the robot controller 518 transmits (at block 2010) to the assembly management system 100 the transmission 1700 with indication of robot ID 1702, barrier ID 1704, location in the barrier 1706 and environmental conditions 1708 of a height in the barrier and indication the robot is not submerged in water and below the high water mark. If (from the no branch of block 2006 or 2012) the height is between the low and high water marks, then control ends without transmitting environmental conditions to the assembly management system 100.

The transmitted environmental condition 1700 in FIG. 19 may be processed by the assembly management system 100 according to the operations of FIG. 9 to generate a revised barrier 200 _(R) to increase the height of the barrier 1206 to a higher barrier 1208 if the water level exceeds the high water mark or decrease the height of the barrier 1208 to a shorter barrier 1206 if the water level is lower than the low water mark.
